About Lumi Trace - One Line Puzzle
Lumi Trace is a one-line drawing puzzle: trace every line of the figure in a single stroke, without going over the same line twice. It looks like string art on a cork board, with brass pins and soft thread.
HOW TO PLAY
• Touch a pin and drag along the lines.
• Cover every line with thread to clear the puzzle.
• You can lift your finger and continue from the same pin.
1,200 PUZZLES IN 8 STAGES
• Sprout, Leaf, Petal, Wind, Echo, Key, Star and Galaxy, 150 puzzles each.
• Every stage is open from the start. Play in any order.
• Earn up to 3 stars per puzzle: no undo and no hint for a perfect clear.
NEW RULES AS YOU GO
• One-way arrows: these lines can only be traced in one direction.
• Double lines: trace them twice.
• Locks and keys: visit the pin with the key before crossing a locked line.
MORE TO DO
• Daily Puzzle: one new puzzle every day.
• Puzzle Maker: draw your own puzzle, check that it can be solved, and share it as a short code.
• 6 board themes: cork, denim, chalkboard, linen, navy felt and rose felt.
• 14 languages, chosen inside the app.
